SAMUEL KRAUSER, OF READING, PENNSYLVANIA.

CIDER OR WINE MILL.

Specification of Letters Patent No. 13,741, dated October 30, 1855.

To all whom 'it may concern:

Be it known that I, SAMUEL KRAUsER, of the city of Reading, in the county Vof Berks and State of Pennsylvania, have invented certain new and useful Improvements in Cider and l/Vine Mills, whereof the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the accompanying drawings, making a part of this specification, in which- Figure l is a perspective view of the machine, Fig. 2 is a longitudinal vertical section of the same, Fig. 3 and M and E in Fig. 1 represent the end View wherein certain operative parts are more clearly eX- hibited, and Fig. 4 is a side view of one of the scraping wheels having a section of the shaft S inserted in its hub. Fig. 5 is a section of the hopper and the connection of the sieve showing its meshes.

The machinery of the mill is mounted upon a rectangular frame consisting of four posts a a, a a connected by suitable side and end rails b b b b b.

The same letters refer to like parts in the different figures.

The form andposition of the hopper is seen in Figs. 1 and 2. 0 0 0 0y are the four converging sides and 0 o2 are vertical sides of the hopper inclosing the sieves.

The apparatus whereby the fruit is reduced to a pomace, consists of two scraping wheels and two stationary cast sieves armed on their inner surfaces with sharp teeth, together with a grinding disk m armed on both its sides with similar teeth. The scraping wheels and disk are operated by the horizontal shaft S which when in operation has a reciprocating as well as a rotary motion communicated to it by means of suitable apparatus hereafter described. The inding disk m is permanently fast upon the shaft S and therefore revolves and reciprocates with it. But the scraping wheels are allowed to have the rotary motion alone. For this purpose the shaft S is permitted to reciprocate freely through their hubs, while its longitudinal projection c (Figs. 2 and 4L), tting loosely into a corresponding recess in the hubs of the said scraping wheels will cause the latter to revolve (but not to reciprocate) with the former. The seves as above mentioned are stationary, the shaft S passing freely through their centers.

The reciprocating motion ofthe shaft S is produced by means of a left and right screw cutupon a part of its length as seen in Figs. l and 2. The reversed threads of the screw are separated by a flange D upon which there is a pin D', as seen in Fig. 2. The opposite ends of the screw are terminated by eccentrics, E E; and F F are tumblers mounted permanently upon a horizontal shaft R upon which they vibrate. Their inner concave surfaces are made to fit easily into the matrix of the screw so that when the screw revolves it will be acted upon by them, the same as it would be by a stationary nut, causing the screw thereby to travel the entire length of its thread either to the right or left, the deviation depending upon which of the tumblers is in gear. The operation o-f the tumblers with reference to the screw is such that while the one is in gear the other is out of gear and a continued rotary mot-ion of the shaft S, will therefore cause it to have a continued reciprocating motion as required. The tumblers are provided with balls T, T, which are used to assist in throwing them in and out of gear.

It has been found by actual experiment that when the machine is in effective operation the lateral pressure of the screw against the tumblers has a tendency to throw them out of gear. To obviate this difliculty two catchers m m have been provided. These catchers are operated by the eccentrics E, E, as hereafter described. The scraping wheels are protected on the outsides by the circular sides K, K, through t-he centers of which the shaft S passes freely. It will be observed that the journals of the shaft S, reciprocate freely, through their boXes or supports L, L. otion is communicated to the shaft S by means of the crank P.

The tumblers and catchers in combination with the right and left screw are operated in the following manner. Suppose the left tumbler F Figs. 1 and 2, is shown in gear, and the eccentric E is close alongside of the tumblers, then by turning the shaft S, the screw will move forward to the left. Now suppose it has t-o move 3 inches. llVhen ithas nearly completed that distance, the eccentric E, will strike the catcher m, andremove its lower lip e, from the shaft R, Figs. l and 2, which supports the tumblers. As soon as the catcher m, is

removed the projection pin D on the ange I), Fig. 2, arrives at the striking point H, on

' the left tumbler F, Fig. 2, and throws it out of gear, simultaneously with this movement. The tumbler F, is thrown in gear and then the screw moves to the right, and so vice versa.

Operation: The hopper being supplied with fruit, and the grinding disk made to revolve, the fruit will be immediately acted upon by the sharp projections upon its sides. The fixed projections upon the inner surfaces of the stationary sieves will also contribute toward reducing the fruit to pomace. As fast as the fruit is reduced to pomace, the latter will be pressed throughA the meshes of t-he sieve, by the gradual approach alternately of the grinding disk toward their inner surfaces. This reciprocating movement of the grinding disk will also enable it eifectually to feed off the entire contents of the hopper, vand facilitate the supply of fruit to its grinding surfaces.

It will be observed that the hopper is provided with a skeleton concave WV, corresponding to the circumference of the grinding disk; a peculiarity in the adaptation of this skeleton concave is that its sides do not touch the sides of the stationary sieves; the spaces thus left open afford an additional avenue for the escape of the confinedv pomace. The oiice of the scraping wheels is to'keep the sieves clean; they also assist to reducethose portions of fruit which hap pen to escape the action of the grinding disk.

Having thus fully described t-he nature of my invention, what I claim therein as new and desire to secure by Letters Patent, 1s-

1. Communicating a reciprocating as well as a rotary motion to the grinding disk, in the manner and for the purposes within described.

2. The use of the grinding disk with its peculiar movements in combination with the two stationary sieves as described and set forth. y

3. The use of the stationary sieves for the purpose of passing the whole or a part of the pomace through their meshes, and also causing them to assist in reducing the fruit to a pomace by providing their inner surfaces with sharp projections as described and set forth within.

4L. The arrangement of the skeleton concave I/V, With reference to sieves in the manner and for the purpose as described.

5. In combination with operating the screw by means of two vibrating tumblers, as described, the use ofthe catchers m, m', in the manner and for the purpose within described.

6. In combination with the side screens, the application of the scraping wheels in the manner and for the purpose within set forth.
